According to the club, a post on Peppers' Instagram story was captioned: "Everything went smooth and I'm recovering well."
The nine-time Pro Bowler made his return to the Panthers in 2017 after spending the first eight years of his career with the franchise.
By season's end, he tied Mario Addison with a team-high 11.0 sacks while forcing a pair of fumbles.
Few have been better at overcoming ailments than Peppers over the years, as he hasn't missed a game since 2007, so it wouldn't at all be surprising if he makes a full recovery in time for the start of the 2018 campaign.
The 38-year-old, who will become an unrestricted free agent in March, has yet to announce if he'll return for a 17th NFL season.
